U-shaped drainage chiteshi inzira yakajairwa yemvura yemudhorobha uye inobata kukosha kukuru mukuronga kwemadhorobha nekuvaka. Ivo havangobudise mvura zvine mutsindo uye kuderedza mafashama emumaguta asi zvakare vanobatsira kuvandudza nharaunda yemadhorobha, kusimudzira hunhu hwese uye mufananidzo weguta.
Chekutanga, migero yedhiraivha yakaita seU inonyatso dhonza mvura uye kudzivirira mafashama emumaguta. Nekukurumidza kukura kwemaguta uye nekuenderera mberi kwekuwedzera kwemaguta, nzvimbo yakafukidzwa nekuvandudzwa kwemaguta yakawedzera, zvichiita kuti masisitimu emvura asashande. Pasina madhiraini akakodzera, mvura inonaya inogona kuungana muguta, zvichiita kuti pave nezvinetso zvakaita semvura mumigwagwa uye kukuvadzwa kwemvura kuzvivakwa. Migero yedhiraivha yakaita seU inounganidza nekuburitsa mvura inonaya, kuve nechokwadi chekuti migwagwa yakaoma uye yakachengeteka yemuguta nezvivakwa.
Chechipiri, madhiraini akaitwa neU anogona kuvandudza nharaunda yemadhorobha. Madhiraini emudhorobha haashande chete chinangwa chemvura asi anobatsirawo mukunakisa nharaunda yemudhorobha. Nzira dzemvura dzakaumbwa neU dzakagadzirwa kuti dzive dzinoyevedza nechimiro chakareruka, kusanganisa nechimiro cheguta uye kuwedzera mufananidzo weguta. Kuburikidza nekungwarira dhizaini uye dhizaini, U-yakaita migero yemvura inogona kuve yemamiriro ekunze, ichiwedzera nzvimbo dzakasvibira muguta, kushongedza nharaunda yemaguta, nekuvandudza hupenyu hwevagari.
Uyezve, madhiraini akaitwa neU-anogona kuwedzera simba reguta rekusimudzira. Zvifambiso zvemadhorobha zvemadhiraivha hazvina kungonangana chete kugadzirisa nyaya dzemvura dzemvura chete asiwo nekuona kuti guta rinogara kwenguva refu. Kuburikidza nekuronga nekugadzira madhiraini akanyatsogadzirwa neU-shaped drainage channel systems, zviwanikwa zvemvura inonaya yemumaguta zvinogona kutarisirwa zvakanaka, kuderedza kuparara kwemvura uye kukurudzira kushandiswa kwedenderedzwa kwemvura, nokudaro kufambisira mberi budiriro yemaguta.
Mukupedzisa, migero yedhiraivha yakaita seU inoita basa rakakosha mukuronga nemadhorobha. Ivo havangogadzirise nyaya dzemafashama emumaguta chete asi zvakare vanosimudzira kunaka kwenzvimbo yemaguta uye kukurudzira budiriro inoenderera. Naizvozvo, muhurongwa hwekuronga nekuvaka kwemaguta, panofanirwa kutariswa kugadzirwa nekuvakwa kwematanho emvura akaita seU, vachishandisa kugona kwavo mukutsigira kusimudzira nekuvandudzwa kwemaguta.
